Capacitance gain adjustment procedure
Review the “Test Considerations” on page 5 and “Gain adjustment
considerations” on page 29 sections before beginning this procedure.
Calibration Mode: Capacitance
1 Apply the input signal shown in the Calibration Point Box.
2 Press to start the adjustment. The Status box displays
CALIBRATING indicates the calibration is in progress.
• Successful completion of each adjustment value is indicated by a
message in the Status box showing PASS.
• An adjustment failure is indicated by a message in the Status box

entered adjustment value to correct the problem and repeat the
adjustment step.
3 Repeat step 1 through 4 for each gain adjustment point shown in the
preset calibration point box.
4 Verify the Capacitance gain adjustments using the “Capacitance
performance verification test” on page 22.
